I have installed a Hayden trans. cooler on my 2005 trailblazer. I got some wrong information as to which line to cut to install my cooler so that the fluid flow was from the factory cooler to the Hayden unit and back to the trans. The fluid now flows from the trans to the Hayden unit and then to the factory cooler. I confirmed this by checking temps on the lines. Can any problems arise from this arrangement?

In the tranny cooler sticky thread it discusses this issue. If you live in a very cold climate this order works to get the tranny up to operating temp easier because flows through the warm radiator last. Warmer climates should have it in reverse order. I would switch it whenever you change your fluid next time
